This invention relates to safety razors oi' the power operated type and,among other objects. aims to provide an improved razor in which theblade and its holder have a ding-- onul path of travel to produce ashear cut as the razor is moved over the surface to be shaved In thedrawings Fig. l. is an elevation showing one embodi inent oi theinvention;

Referring particularly to the drawings, the preferred embodiment oi theinvention is there shor as comprising; a handle 10 ha vino;reciprocating mechanism mounted at one end to which is connected anadapter 11 carrying the head of a satety razor. The device is adaptedfor use with the head or holder ot any conventional. safety razor theparticular head shown being); of. a. Well known type.

Herein, the handle 10 is shown as being tubular to receive the drivingmeans for the hca d. l or this pnrp so, a rotatal'ile spindle 12 isjournaled in suitable bearings 18 and i1" and is adapted. to be rotatedby means ot a flexible shaft 15 connected to its lower end and extendingto any source oit' power such as a small electric motor (not shown Theflexible shatt may be of any conventional construction preferablyhavinp; a surrounding;- housing; or armor l6 which may be secure i an asleeve 17 in the lower end of the ham: The upper end ot the shafthas anenla head 18 Whose lower taco abuts the upper :t'acc oil the bearing 13and Whose upper face is substantially flush with the upper surface of anenlarged annular flange l9 termed at the upper end of the handle 10. Acollar 20 is adjustably secured to the spindle 12 and abuts the lowerface of the bearing; 13 to prevent longitudinal movement of the spindle.The collar may be secured to the spindle by 1929 Serial No. 373,531.

means of a set screw 21 which may be adjusted by inserting a suitabletool through an apertn re 22 in the Wall oi? the handle.

Ellid ably mounted on the flange 19 above the head 18 and between thedovetailed guides 23 is a rectangular plate or block 24 having alongitudinally disposed attaching lug 25 exten d inn upwardly therefrom.

To impart movement to the block, a tran versely extending: elongatedrecess 26 is provided in the underside thereof and a crank pin 27extends upwardly from the head 18 into the recess so that as the spindle12 is rotates the block is caused to reciprocate between the guides 23.The guides 23 are removably secured to the flange 1.9 by bolts threadedthrough and extending above them. it housing is provided for thereciprocating mechanism, and is preferably in the form of an annularplate 28 having a depending pe- 7o ripheral flange 29 snugly fittingover the flange 19. The plate 28 is spaced above the guides and slightlybeneath the upper surface of the hip; 25 and is held in place by meansof s iacinp; members 30 on the bolts between the plate and the guidesand nuts 31 on the bolts above the plate. The plate has an elongatedopening 32 therein to permit movement of the lug 25. v

The adapter 11 carrying the razor head is go herein shown as being inthe form of a bracket having arms 33 and 34 arranged substantially atright angles to each other and strengthened by a brare As shown in Fig.3 the free end of the arm 3t is curved s5 inwardly as indicated at 36and to the out or surface of the curved portion is secured a guard plate37 and a blade 38 by means of a clamp 39 and thumb nut 40. The curvatureof the bracket arm is preferably such that so when the outer cuttingedge of the blade, Which indicated at a1, is applied to the surface tobe shaved, the handle 10 Will extend substantially at right angles tosaid surface. The other arm 33 of the bracket is removably secured tothe lug 25 by means of slots l2 in the arm coacting With a headed member43 at one end of the lug and a clamping thumb bolt 44 at the other end.

As shown in Figs. 2 and 4:, the arm 34 is 10 arranged at an acute angleto the lug so that the cutting edge of the blade is at an angle to thepath of travel of the lug. This causes the blade to produce a. shearingcut as it is moved over the surface to be shaved.

In using the device, the cutting edge il is applied to the surface to beshaved and with the handle extending substantially at right angles tothe surface, the Whole device is moved ahead and the reciprocating headcauses the blade to shave a path wider than the length of the blade.

Whenever the path of travel of the device over the surface to be shaved,the head will always be reciprocated at an angle to that path andproduce the desired shearing cut. Furthermore, the blade is notreciprocated in its holder, which would produce friction and heat theblade to destroy its temper.

a Thus, it is anticipated that the device may be employed without injuryto the user when travelling on trains, aeroplanes, etc.

The improved devices can be stored in relatively small cases and arevery easily assembled. They can be connected to a small electric motorand will give a clean shave in considerably less time than is requiredby the old hand method. Moreover, the parts can be manufactured at a lowcost.

Obviously, the present invention is not restricted to the particularembodiment thereof herein shown and described. Moreover, it is notindispensable that all the features of the invention be used conjointly,since they may be employed advantageously in vari ous combinations andsub-combinations What is claimed is 1. In a safety razor, a handle; arotatable spindle in the handle; a reciprocable block mounted at one endof the handle and operatively connected to be reciprocated by thespindle; a bracket removably secured to the block; and a. safety razorhead assembly carried by the bracket, the cutting edge of the razorblade in said head being arranged at an acute angle to the path oftravel of the block.

2. A safety razor comprising, in combination, a handle; an enlargedflange at one end of the handle; a reciprocable block mounted on theflange and having an attaching lug thereon; a housing secured to theflange and covering the block, said housing having an elongated slottherein to permit the lug to extend therethrough; means for impartingmovement to the block: a safety razor head secured to the lug; and razorblade associated with the head, the cutting edge of the blade beingarranged at an angle to the path of travel of the block.

3. A safety razor comprising, in combination, a tubular handle; anenlarged annular 1 guides; said block having a transverse elongatedrecess in the bottom thereof; a rotatable spindle j ournaled within thehandle and having a crank pin extending into the recess to impartreciprocating movement to the block when the spindle is rotated; anattaching lug on the block; an angle bracket having one arm secured tothe lug and the outer free end curved inwardly; a guard plate, razorblade and clamping plate secured to the curved end of the bracket arm,the cutting edge of said blade being at an angle to the path of travelof the block.

4:. A safety razor comprising, in combination, a tubular handle; anenlarged annular flange at one end thereof; a pair of guides secured tothe flange; a rectangular block slidably mounted on the flange betweenthe guides; said block having a transverse elongated recess in thebottom thereof; a rotatable spindle journaled within the handle andhaving a crank pin extending into the recess to impart reciprocatingmovement to the block when the spindle is rotated; an attaching lug onthe block; an angle bracket having one arm secured to the lug and theouter free end curved inwardly; a guard plate, razor blade and clampingplate secured to the curved end of the bracket arm; a cover platebetween the block and the bracket and.

having an opening therein for the lug; and a marginal depending flangeon the plate fitting over the flange on the handle.

In testimony, that I claim the foregoing as my own, I have hereto afixedmy signature. p
